Glass-Steel®, Inc. custom fabricates fiberglass stop plates and guide systems to meet project-specific dimensions and installation requirements. Slide guides are typically fiberglass and can also be furnished in aluminum or stainless steel.

Stop plates do not utilize neoprene seals. Instead, the head pressure of the water being controlled forces the stop plate against the guide to create the seal.

Fiberglass Stop Plates Technical Brochure

What are fiberglass stop plates used for?

Fiberglass stop plates are used for temporary storage and control of water in flow channels at water and wastewater treatment plants. Glass-Steel®, Inc. custom fabricates stop plates to meet the requirements of each application.

Can Glass-Steel®, Inc. custom fabricate stop plates?

Yes. Glass-Steel®, Inc. fabricates fiberglass stop plates with dimensions, thickness and reinforcement selected according to the requirements of the particular application.

What materials are used for fiberglass stop plates?

For most water and wastewater applications, Glass-Steel®, Inc. uses isophthalic polyester pultrusions. Custom resin systems, including bisphenol and vinyl ester systems, are also available.

Do fiberglass stop plates use neoprene seals?

No. Fiberglass stop plates do not utilize neoprene seals. The stop plate relies on the head pressure of the water being controlled to force the plate against the guide and create a seal.

What guide materials are available for stop plates?

Slide guides are typically fiberglass but can also be furnished in aluminum or stainless steel depending on project requirements.

How are fiberglass stop plates reinforced?

Reinforced stop plates generally utilize 1/4-inch pultruded plate with fiberglass stiffeners sized according to the load requirements of the particular application. Thickness and reinforcement can vary by project.

What are the benefits of fiberglass stop plates?

Fiberglass stop plates provide a lower-cost, corrosion-resistant alternative to comparable aluminum or stainless steel stop plates. They are also lightweight and easier to handle.
